查询词典 X's

Classically, the skin lesions occur perinatally in four successive stages: inflammatory vesicular (stage 1), verrucous (stage 2), hyperpigmented (stage 3), and scarring (stage 4), along the lines of Blaschko, reflecting the somatic mosaicism of X-chromosome inactivation in female patients.

典型的皮肤表现发生在周产期并可区分为四个阶段：发炎水泡，疣状增生，色素沉著和疤痕形成，而这些病灶都沿著Blaschko's line分布。它代表了女性患者身上一种嵌合型X染色体异常的现象。

For two decades before Loma Linda opened the world's first hospital-based proton center in 1990, standard x-ray radiation therapy was one of the standard methods for treating prostate cancer.

The drug release experiments in vitro indicated that with the increase of PLA molecular weight, the drug release rates decreased. 4ac releasing from 4ac-PLA-NP could be characterized by Weibull's equation. The interaction between 4ac and others compositions was not detected by DSC. The peak position of 4ac in DSC did not changed comparing 4ac with 4ac-PLA-NP lyophilize injection. Thc X-ray result showed that the peak of 4ac-PLA-NP was piled up between 4ac and other compositions.

差示扫描量热分析结果表明药物与各组分之间无明显的相互作用，制成4ac-PLA-NP冻干针剂后，其放热峰主要表现为聚乳酸的放热峰：X-射线衍射结果表明药物与载体间无相互作用，4ac-PLA-NP主要表现为4ac与载体之间的叠加峰；TLC、FT-IR也同样表明药物与载体无相互作用，它们之间是一种物理结合，并未有新物质生成。

6 The caryotype of giant panda's fibroblasts can be divided into two groups based on centromericindex.Group one of No.l-17 and X chromosomes is metacentric or submetacentric;Group two ofNo.18-20 is acrocentric little chromosomes.

第四代大熊猫皮肤成纤维细胞(PF4)染色体组型：2n＝42，根据着丝粒指数，总体可将其分为两种类型，1-17号常染色体和X染色体为中部或亚中着丝粒，18-20号常染色体为小型近端着丝粒。

Examples include myotonic dystrophy, Huntington's disease, fragile X mental retardation, and several other neurologic disorders.

The nepeta x faasenii, one of the first hardy plants in flowers is always loyal to one's post and stands out next to a yellow chrysanthemum.

nepeta x faasenii，第一个能吃苦植物一开着花总忠实在一个人岗位并且显著紧挨着一朵黄的菊花。

The microstructure evolution and composition distribution of the 7A55 cast and homogenized alloy were studied by optical microscopy, scanning electron microcopy, energy dispersive spectrometer, transmission electron microscopy and X-ray diffractometry. The homogenizing and overburnt temperatures of the alloy were determined. Meanwhile, the diffusion kinetics of the alloy elements during homogenizing treatment was investigated and the homogenizing kinetic equation was deduced according to Fick's First Law of diffusion. The diffusion of alloy elements, precipitation of Al3Zr particles and the conglomeration and globe of the insoluble phases were explained by the equation during homogenization.

摘 要：采用光学显微镜、扫描电镜、能谱分析、透射电镜和X射线衍射分析等研究了7A55合金铸态与均匀化显微组织演化与成分分布，确定了该合金的均匀化处理温度与过烧温度，研究了铸锭均匀化动力学过程，利用菲克定理导出了均匀化动力学方程，利用动力学方程对均匀化过程中合金元素的扩散、 Al3Zr的析出、难熔相的聚集和球化现象进行了解释。

目的 分析骨折带锁髓内针固定后髓内针周围骨反应的X线表现，并探讨其形成机制。

Individuals with one X and no Y chromosome are phenotypically females but have a group of physical abnormalities including dwarfism and failure of ovarian development known as Turner's syndrome.

含有一个X而无Y染色体的患者表型为女性，但有一组机体异常表现，包括侏儒郑和卵巢不发育，称为Turner综合症。
